0.59x+1490-0.68x=0
Tangohia te 0.68x mai i ngā taha e rua.
-0.09x+1490=0
Pahekotia te 0.59x me -0.68x, ka -0.09x.
-0.09x=-1490
Tangohia te 1490 mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
x=\frac{-1490}{-0.09}
Whakawehea ngā taha e rua ki te -0.09.
x=\frac{-149000}{-9}
Whakarohaina te \frac{-1490}{-0.09} mā te whakarea i te taurunga me te tauraro ki te 100.
x=\frac{149000}{9}
Ka taea te hautanga \frac{-149000}{-9} te whakamāmā ki te \frac{149000}{9} mā te tango tahi i te tohu tōraro i te taurunga me te tauraro.
